Abstract: A safety improvement for a Motorcycles warning actuation switch. The hand grip commonly made of rubber or leather material incorporates a ribbon switch that encompasses a 360 degree area. The ribbon switch is preferably placed in the inside end of the hand grip. Normal hand placement on the hand grip will not actuate the warning device unless deliberate. The ribbon switch is a momentary switching device. As the hand grip is depressed or squeezed at any point around its 360 degree arc, the ribbon switch contacts are closed, therefore actuating the warning device, ordinarily a horn.
Abstract: A counterforce spring assembly for printed circuit board test fixtures is provided. A number of counterforce spring assemblies are provided in an array between the top plate and probe plate of the test fixture. Each counterforce spring assembly includes a support cup residing in an aperture through the probe plate. A compression spring resides in the support cup and provides spring-biasing of the top plate to the probe plate during the UUT testing cycle. Each counterforce spring assembly includes a circumferential flange to limit downward travel of the top plate toward the probe plate. Each assembly is small enough to fit between probe apertures corresponding to component leads of the UUT. The counterforce spring assemblies can be freely placed underneath the top plate to provide even spring-biasing thereof to prevent bowing and bending of the top plate which often causes errors in the testing of printed circuit boards.
