Title: Latch and switch actuator interlock safety structure for electronic component module operable during insertion and removal of connector members

Abstract: An actuator controlled switch mounted on an electronic component module is operative to remove electrical power from the module during plug-in or removal of the module from a support frame. A latch and the actuator are pivotally mounted in parallel relation on the module and the latch is urged against a fixed support frame member. During plug-in and removal, a lateral extension of the latch forces the actuator to hold the module switch off. When the module is fully engaged, the latch is removably displaced from the actuator whereby the actutor can be pivoted to turn the module switch on and off.
