Abstract: An in line switch device (1) includes a switch housing (3, 4) providing a switch component chamber. A switch actuator (8, 9) is operable from the exterior of the switch housing (3, 4). At least two sets of switch terminals (17, 18, 19, 20, 21, 22) are accessible from the exterior of the switch component chamber and are covered by a removable closure or respective removable closures (26, 27). The removable closure(s) has two cable apertures (28) for passage of respective power cables to be connected to respective sets of switch terminals (17, 18, 19, 20, 21, 22). A first sealing device (29, 30) is associated with each cable aperture (28) for sealing around the associated power cable. The removable closure(s) (26, 27) are engaged with the switch housing (3, 4) with one or more second sealing devices (14, 15) provided at the interface between the or each removable closure (26, 27) and the housing (3, 4).

Abstract: A gas burner for use in gas fireplaces provides a yellow flickering flame such as that seen in a real wood fire while maintaining a low level of carbon monoxide production. The gas burner is simple in design and compact in size and may be used in either direct vent or gravity vent gas fireplaces. An air baffle plate may be affixed to the rear of the gas burner to maintain the critical balance between primary and secondary combustion air when using liquid propane gas.
