<p>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 ofswitch terminals (17,18,19,20,21,22) are accessible from the cxterior 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). The switch (3,4) is sealed, at least externally of the closure(s) (26,27) to protect against the ingress of moisture into the switch component chamber. <IMAGE></p> |
