  • Patent number: 6093900
    Abstract: An electrical switch (26) is mounted in a rigid housing in the form of a control handle (10), where the housing has a soft flexible covering (32) with a portion (40) that can be depressed to operate the switch. The housing is in the form of a shell with first and second separately molded shell parts (14,16). The first shell part has a hole (24) in it that is aligned with the switch actuator, and the covering is overmolded onto the first shell, with the portion of the covering lying over the hole in the first shell being thickened at the middle (44) of the hole to indicate the area to be depressed and for more comfortable depression.

  • Patent number: 5807122
    Abstract: An adapter (1, FIG. 1) is provided for the connection of an optoelectronic component such as an LED (light emitting diode) (2) to a circuit board (8) that lies in a case (34), wherein the adaptor positions the LED close to a window (32) in the top wall (30) of the case. The adapter has a pair of passages (4, 5) for holding conductors (11, 12) that connect terminals of the LED to SMD (surface mount device) contacts (6) that connect to the circuit board. The adapter holds the LED high enough above the circuit board, for the upper face (36) of the LED to lie in or close to the level of the window, so light from the LED can be readily seen from outside the case.
