Secure Enabling Switch

Contact module able to set up electric contact between two fixed contacts (14) by means of a mobile contact (15) when pressure is applied to a transmission member in an actuation direction (X), comprising:

• a body (7) carrying the two fixed contacts (14),
• a transmission member (3,5) carrying the mobile contact (15) and sliding within said body (7) in the actuation direction (X), wherein:
• said transmission member is formed of two parts (3,5) and is able to contract in the actuation direction (X) when excessive pressure is applied to said member after electric contact has been set up,
• the mobile contact (15) is able to separate itself from at least one fixed contact (14) under the action of elastic means (12) when the transmission member (3, 5) is in its contracted state,
• said transmission member comprises:
• an actuator element (3) sliding within said body (7) in the actuation direction (X) against prompting by at least one elastic means (13),
• a contact-holder (5) carrying the mobile contact (15), slidingly mounted in said direction (X) in a housing (30) of the actuator element (3) by means of an indexing system (16, 17) which can retract into said housing (30) under the effect of excessive pressure applied to the actuator element (3) when the contact-holder (5) lies in abutment on the body (7),
• said mobile contact (15) being able to slide in said direction (X) on the contact-holder (5) against prompting action by elastic means (11), wherein the indexing system of the contact-holder (5) comprises two beads (16) connected by elastic means (17) substantially perpendicular to the actuation direction (X).
