Title:
SEAL STRUCTURE FOR CHANGE OVER SWITCH
Document Type and Number:
WIPO Patent Application WO/2006/022348
Kind Code:
A1
Abstract:
A seal structure for a change over switch, capable of always maintaining a tightening force of a packing in a stable state without being affected by an assembly fixation force acting between a base board and a lid body, and capable of simply and reliably sealing the contact section between the base board and the lid body. In a seal structure for a change over switch (10), a switch case is constructed from a base board (12) having fixed contacts (13) and from a lid body (14) assembled so as to be in contact with the periphery of the base board (12) to form a sealed inner space inside the switch case. A movable board (15) is provided in the switch case (11), and the movable board has a movable contact (16) that slides on the fixed contacts (13) to perform contact change over. Annular packing (18) for sealing the contact section between the base board (12) and the lid body (14) is placed between the base board (12) and the lid body (14). The direction of tightening of the annular packing (18) between the base board (12) and the lid body (14) is orthogonal to the direction (Y) of assembling the base board (12) and the lid body (14).
