ABSTRACT:
This invention relates to a safety belt buckle having an electrical switch means located beneath the buckle base of the buckle and operable by insertion of a tongue plate into latching engagement with a latching mechanism within the buckle. The switch is constructed of inexpensive elongated contact strips or arms which are formed with integral locating means for press fit engagement into molded portions of a plastic cover housing thereby aligning and holding the contacts in the desired position relative to one another. An actuator for actuating the contact arms is preferably in the form of a lever pivotally mounted in the cover housing and having the first cam surface for positively camming one contact arm from the other contact and a second cam surface for engaging the other contact and driving it away from the first contact arm. A bolster spring means returns the actuating lever to its tongue plate sensing position. Suitable insulating means are provided for protecting the contact arms from contact with the metal operating parts of the latching mechanism of the buckle.
