12mm Waterproof Push Button Switch

A 12mm momentary push button is a type of switch that is designed to withstand exposure to water and moisture. It is commonly used in environments where water is present, such as marine or outdoor applications, where it may be exposed to rain or splashing.

The push button has a 12mm diameter and is made up of a metal or plastic housing, a plunger or button, and an electrical contact mechanism. The plunger or button is the part of the switch that is actually pushed by the user, which activates the electrical contact mechanism to open or close a circuit.

The housing of the push button is typically made from a durable material, such as stainless steel, that is resistant to corrosion and rust. It is also designed to provide a seal around the electrical components, which prevents water from entering and causing damage.

The electrical contact mechanism of the push button is what enables it to switch on or off an electrical circuit. It is typically made up of two metal contacts, which are separated until the plunger or button is pushed. When the plunger or button is pushed, the contacts touch, completing the circuit and allowing electrical current to flow.

Overall, a 12mm push button is an essential component in any application where water resistance is required. They are commonly used in marine electronics, outdoor lighting controls, and medical equipment where safety and reliability are critical. Having a waterproof push button ensures that the equipment will continue to function properly and safely, even in wet or humid conditions.
