Abstract
A switch is mounted on a plate within a housing having a housing body with a port and a removable housing cover. A switch actuator rod is mounted on a pivot within a sleeve that may be coupled to the housing so that the rod extends through the port and engages the switch within the housing. A linear actuator rod is slideably mounted within a sleeve which also may be coupled to the housing so that the rod extends through the port and engages the switch. A spring is mounted on the housing cover in a direction traverse to the arc through which the swing actuator rod pivots so that it engages the end of rod and biases it away from the switch. By removing the cover, moving the rod to the opposite end of its arc, and replacing the cover, the direction of engagement of the rod with the spring may be changed. The switch plate is movable along the rod's arc of pivot so that the switch trip point along the arc may be adjusted.
