Abstract

An improved inertia switch having a variable threshold and operating time comprises a flywheel, a driving member, electrical contact elements carried respectively by the driving member and the flywheel and return means coupled between the driving member and the flywheel. The contact element carried by the flywheel comprises on the one hand a contact terminal integral with a support coupled by friction to the flywheel, the contact terminal co-operating with a part of the contact carried by the driving member, and on the other hand, a contact surface integral with the flywheel co-operating with a second contact part carried by the driving member. The switch is particularly applicable for detecting imminent locking of a vehicle wheel.
