Push lock switch with dual function self-biasing slider contact

A push lock switch comprising:

• a slider moveable between two positions;
• a locking pin means for operationally engaging and disengaging a cam groove wherein said locking pin means is operationally mounted to said slider;
• and
• a conductive resilient member means connected to said slider for electrically contacting fixed contacts to perform a switching function when said slider moves between said positions and for pressing said locking pin means against said cam groove, said conductive resilient member having a pressing portion for performing said pressing, a movable contact for performing said electrical contacting, and a mounting portion for fixing the conductive resilient member to the slider, wherein the pressing portion extends in one direction from the mounting portion, and said movable contact extends in a second direction from the mounting portion and wherein the first direction is substantially opposite to the second direction.

A push lock switch comprising:

• a switch body including an inner wall defining a chamber, a plurality of terminals each having a fixed contact, a cam groove defined in said wall, an engaging portion defined on said wall, and an opening to the chamber;
• a slider accommodated in said chamber so as to be movable between a projecting position and a retracted position, the slider being adapted to be inserted into the opening during assembly of the switch in a direction toward the fixed contacts, said slider being spring biased toward the opening when the switch is assembled;
• a lock pin having a first end fitted in said cam groove and selectively engaging the engaging portion and a second end connected to said slider such that, when said first end is engaged with said engaging portion, said slider is retained at said retracted position;
• a movable contact joined to slider for electrically contacting said fixed contacts of said terminals in accordance with movement of said slider;
• a pressing member for pressing the first end of the lock pin against the bottom of the groove;
• and
• wherein the groove is open toward the opening so that the first end of the lock pin can enter the groove from the direction of the opening when the slider is inserted into the opening during assembly.
