Snap action switches are a type of limit switch that can open and/or close an electrical circuit very quickly. Typically, these switches are triggered by human force or when a physical item is applied to the actuator. The snap action occurs because of the rapid movement of the spring-assisted moving contacts, jumping from one position to another. These switches are often used in thermostat controls, vending machines, machine tools, pressure sensors, and medical devices. Zoro carries many types of switches and accessories like push button switches, rocker switches, rotary switches, and toggle switches.
