Leyu provides industrial switches for machinery, electrical control panels, automation equipment and operator-control systems.
The product range includes rotary switches, push button switches and piezo switches, allowing designers to select different operating methods for circuit selection, start/stop control, reset functions and demanding industrial environments.
The correct industrial switch should be selected according to its control function, mounting size, contact configuration, electrical rating, operating method, housing material and required IP protection.
Switch Type | Main Selection Factors | Typical Function |
|---|---|---|
Rotary Switch | Poles, positions, current | Mode and circuit selection |
Push Button Switch | Mounting size, contact, action | Start, stop and reset |
Piezo Switch | Mounting size, material, protection | Frequent operation and wet environments |
A rotary switch allows an operator to select between multiple electrical positions or circuits by rotating the control knob.
It can be used for:
Mode selection
Circuit changeover
Motor control
Measurement selection
Multi-position control
Equipment function selection
When selecting a rotary switch, check:
Number of Poles → Number of Positions → Voltage → Current → Switching Function
Rotary switches are particularly useful where several control states must be selected from one operator interface.
A push button switch provides simple operator control for industrial panels and equipment.
Common functions include:
Start
Stop
Reset
Power control
Auxiliary control
Signal activation
Available configurations may include different:
Mounting diameters
Contact combinations
Momentary or latching actions
Illuminated or non-illuminated designs
Housing materials
Environmental protection levels
When selecting a push button, first confirm the required panel mounting size and electrical contact function.
A piezo switch uses pressure applied to a piezoelectric element to generate the switching signal rather than relying on a conventional moving mechanical mechanism.
This construction can make piezo switches suitable for applications requiring:
Frequent operation
Stainless steel surfaces
Wet environments
Easy-to-clean interfaces
Industrial control panels
Public or self-service equipment
Selected models may also provide illumination and enhanced environmental protection.
Always verify the exact IP rating and electrical specification of the selected model.
You need:
Multiple positions
Mode selection
Circuit switching
Operator-selectable settings
You need:
Start/stop
Reset
Momentary control
Simple operator input
You need:
Minimal mechanical movement
Frequent operation
Stainless steel construction
Enhanced environmental protection
A clean operator interface
Panel-mounted switches must fit the available installation opening.
Common industrial switch mounting sizes can include different diameters depending on series.
Before ordering, confirm:
Mounting Hole: ___ mm
Panel Thickness: ___ mm
Available Rear Depth: ___ mm
Do not select a switch based only on the front-panel appearance.
A momentary switch changes state only while it is being operated or according to its designed momentary action.
Common applications include:
Start
Reset
Signal input
Temporary control
A latching or self-locking switch maintains its selected state until it is operated again.
Common uses include:
ON/OFF control
Equipment enable
Mode activation
Choose the operating action according to the actual control circuit.
Industrial push buttons and other switches may use different contact configurations.
Common examples include:
The circuit closes when the switch is activated.
The circuit opens when the switch is activated.
Provides both normally open and normally closed contact functions for control circuits requiring both states.
Always confirm the contact configuration required by your electrical schematic.
Do not select an industrial switch by appearance or mounting diameter alone.
Confirm:
AC or DC load
Operating voltage
Operating current
Load type
Switching frequency
Electrical ratings can vary significantly according to switch type and contact design.
If the load is inductive, motor-driven or otherwise demanding, provide the actual load characteristics when requesting a recommendation.
Industrial switches may be installed in environments involving:
Dust
Moisture
Water splash
Outdoor exposure
Frequent cleaning
When environmental protection matters, check the specific product IP rating.
Do not assume that every switch within one category has the same waterproof rating.
Also consider protection of:
Rear terminals
Cable connections
Panel sealing
Wiring
The complete installation must be evaluated, not only the switch front surface.
Depending on the series, industrial switches may use materials such as:
Plastic
Nickel-plated brass
Stainless steel
Suitable for applications requiring a durable panel-mounted appearance.
Can be considered for demanding environments where corrosion resistance and surface durability are important.
May provide a lightweight and cost-effective option for suitable indoor equipment.
Choose between:
ON/OFF
Start
Stop
Reset
Momentary
Latching
Multi-position
Circuit selection
Check hole diameter, panel thickness and rear installation space.
Provide actual voltage, current and load type.
Choose NO, NC or combined contacts as required.
Choose:
Rotary
Mechanical push button
Piezo operation
Illuminated switches can provide visual status indication.
Confirm required:
IP protection
Housing material
Operating temperature
Outdoor suitability
For machine start, stop, reset and operating-mode selection.
For operator commands and equipment control.
For manual control and circuit-selection interfaces.
Selected IP-rated switches can be considered where moisture and environmental protection are required.
Metal and piezo switches can be used in suitable public-control interfaces.
An industrial switch is an electrical control component designed for machinery, control panels and related equipment. Different types provide ON/OFF, momentary, latching or multi-position control.
A rotary switch is generally used for selecting between multiple positions or functions. A push button is typically used for direct actions such as start, stop or reset.
A momentary switch provides temporary operation, while a latching switch remains in its selected state until it is operated again.
Measure the panel mounting hole, panel thickness and available installation depth before choosing a switch.
No. IP protection varies by model. Confirm the exact IP rating required for your installation.
