Abstract: A remote control device for an automotive vehicle wherein a transmitter (10) is received in a holder (2), with side-marker lights and taillights staying on, to connect holder-side contacts (3, 4) to transmitter-side contacts (16, 17), and the transmitter (10) is removed from the holder (2) to disconnect the transmitter-side contacts (16, 17) from the holder-side contacts (3, 4). A differentiating circuit (21) detects the disconnection of the transmitter-side contacts (16, 17) from the holder-side contacts (3, 4) by the removal of the transmitter (10) in the on position of the side-marker lights and taillights, and a timer (22) clocks a predetermined timer time over which LEDs illuminate manipulation keys (12) of the transmitter (10). Only the removal of the remote control transmitter from the holder permits the manipulation keys to be readily illuminated.

Abstract: There is disclosed a push button switch which comprises rubber contacts each including a contact portion (311), a flared portion (312) formed integrally with the periphery of the contact portion (311), and a ring-shaped portion (313) formed integrally with a lower end of the flared portion (312) and disposed on a printed board (1) wherein the following relation is satisfied: 0.3.ltoreq.d/a.ltoreq.0.7, 4.ltoreq.d/t.ltoreq.6, 1.0.ltoreq.d/h.ltoreq.1.4, 150.degree..ltoreq..theta..ltoreq.165.degree., 1.5.ltoreq.h.ltoreq.3 where t is the thickness of the flared portion (312), d is the length of the flared portion (312), a is an inner diameter of the ring-shaped portion (313), .theta. is an opening angle formed by an inner side surface of the flared portion (312) and a top surface of the printed board (1), and h is the distance between a bottom surface of a conductor (32) and the top surface of the printed board (1).

Abstract: There is disclosed a seesaw switch which includes two rubber contacts (4a, 4b) juxtaposed on a printed board (2) within a case (1) defining a through hole (6) above the rubber contacts (4a, 4b), a key button (12) inserted in the through hole (6) from inside the case (1) and placed on pushing elements (5a, 5b) formed on the rubber contacts (4a, 4b), and a collar portion (22) formed at lower end of the key button (12) and abutting against an inner surface of the case (1) on the periphery of the through hole (6).

Abstract: A multi-directional switch (1) comprises a joy stick (6) which is inclined for selective operation of a plurality of switch portions. The joy stick (6) includes a support portion (6a) supported pivotally about the bottom end thereof; a slidable contact spherical portion (6b) bulging from the top end of the support portion (6a) and having a spherical surface (6e) slidably abutting throughout the circumference thereof against the inner peripheral surface of a through hole (5a) when pivoted; and an operating portion (6c) projecting through the through hole (5a) adjacent the spherical surface (6e). The outer periphery of a flat surface (6d) of the slidable contact spherical portion (6b) of the joy stick (6) is supported at four circumferentially spaced positions so that the joy stick (6) is returned to a neutral position by the elastic restoring force of the switch portions.
