Metal Power Push Button Switch

1. Product View

16mm momentary Flush Head Metal Button Switch with Power Symbol and Ring LED Indication. Mainly used for equipment power-on triggering, soft reset and status indication. 

This model is self-resetting (momentary): Press down to conduct, release to disconnect, output pulse / trigger signal, suitable for connection to MCU, control board or signal loop; But It is not fit to directly connect and disconnect the strong power main circuit.

The flat type design makes the button basically flush with the panel, which can reduce bumping and accidental touch. The metal shell is suitable for the dust, oil and general water splash environment of machine tool control cabinet, CNC, assembly line, test tooling, etc. The panel has a power symbol by itself, which can reduce the extra screen printing of the whole machine panel.

2. Product Specification

The specific rated current and panel thickness as well as wiring specifications shall be subject to the product specification or samples confirmation result. For IP67 rating, panel sealing shall be done in accordance with installation requirements.

4. The key selling points

1. Soft power solution suitable for MCU/control boards: self-resetting with pulse output only; triggered on press and disconnected on release, without latching the power supply directly.

2. Reduced panel silkscreen: built-in power symbol for intuitive identification of the power button, widely used on export equipment and complete machine panels.

3. Flat head design for accidental press prevention: flush panel mounting, ideal for gloved operation and equipment panels with limited space.

4. Metal housing for industrial environments: stainless steel or nickel-plated brass available, supporting IP65 or IP67 protection, suitable for dusty, oily and splashing-water scenarios.

5. 16mm size saves panel space: more compact than 22mm industrial pushbuttons, perfect for small-panel devices such as instruments, energy storage equipment, UPS and vehicle-mounted electronic controls.

6. Separate indicator light and contact terminals: LED indicators can be selected according to system voltage and color requirements for more flexible wiring.

5. FAQ

Q1: Is this a latching or momentary ? What is diffrence from 16mm latching power button ?

A1: It's self-rest, suitable for MCU power-on trigger, soft reset. Latching type is keep the state on when you press down it, press again, it's off, it suit for low-power circuit.

Select the self-locking version if power needs to remain connected; choose this model for soft power/soft reset solutions.

Q2：How to select the power logo and no mark ?
A：Power symbol version: pre-printed icon, no extra silkscreen, perfect for main power key.Blank version: flat unmarked face, for reset, start or customer custom marking.

Q3：What environments are metal buttons suitable for compared with plastic buttons?
A：Metal: scratch, oil & impact resistant, IP65/IP67 optional, for damp, oily, outdoor, splash areas.Plastic: low cost, good insulation, weaker protection & aging resistance.Note: Ground metal panel per system requirement.

Q4：How to select 16mm or 22mm metal switch ?
A：16mm compact cutout: for signal devices like small instruments, energy storage, UPS, vehicle control.

22mm: commonly for high-power cabinet start/stop.Contacts for signal only, not for high-voltage main circuit. 220V LED optional; LED circuit separate.
