Electronic Switch

Switches are commonly employed an input devices to indicate the presence or absence of a particular condition in a system or process that is being monitored and controlled. Limit switches also are available with time delayed contact transfer. This type is useful in detecting jams that cause the limit switch to remain actuated beyond a predetermined time interval. Limit switches are primarily used in reciprocating actuators, or where position memory or manual reset is required. Spring return limit switches automatically reset when actuating force is removed.
