Pushbutton switches are widely used in various industrial, commercial and residential applications. The PS2-221G is a popular pushbutton switch that is designed to provide reliable switching action in high-speed, high-vibration environments. It is a single-pole, double-throw switch that is actuated by a plunger-style button. A variety of configurations are available, including momentary and maintained, self-latching and non-latching, and a range of switch ratings and operating temperatures.

The PS2-221G is composed of a body, a contact block, a plunger, a terminal block, and an actuator. The body is constructed of polycarbonate and ABS plastic, is corrosion resistant, and offers a high degree of insulation for safety. The contact block contains the switch’s contacts, which are made of copper alloy. The plunger is a spring-loaded button that moves in and out depending on whether the switch is in the on or off position. The terminal block provides connections for electrical wiring and is available in a variety of styles, including solder or crimp. The actuator is a metal plate that is used to activate the switch.

The PS2-221G is commonly used in applications that require reliable switching action in high-speed, high-vibration environments, such as automotive, industrial, and aerospace. It is suitable for use in applications where the switch must be able to continually interrupt an electrical circuit, such as an airbag system. The switch is rated for a maximum current of 1 amp and a maximum voltage of 250V AC. It has a contact resistance of less than 30 mΩ, an insulation resistance of greater than 500 mΩ, and a dielectric strength of 1000V AC. The switch is also designed to operate at a temperature range of -40 to +85°C.

The operating principle of the PS2-221G is simple. When the plunger is pressed, the contact block is pulled against the body and the contacts close, completing the circuit. When the plunger is released, the contact block releases and the contacts open, breaking the circuit. This same principle can be found in other types of push-button switches, such as toggle and rocker switches. The PS2-221G is designed to be reliable and rugged, providing a secure and consistent switching action for years of trouble free service.
