。The drawings show one embodiment of the present invention, in which Fig. 1 is a vertical sectional side view, Fig. 2 is a diagram of the fixed contact arrangement of the insulator, Fig. 3 is a front view with the insulator removed, and Fig. 4 is a diagram showing the arrangement of fixed contacts of the insulator. FIG. 5 is a longitudinal cross-sectional side view of a portion different from FIG. 1, FIG. 5 is a cross-sectional plan view, and FIG. 6 is a time chart. In the figure, 4 and 5 are first and second (7) fixed contact groups, 6 is a cathode fixed contact, 7 is a load fixed contact, 8 and 9 are anode fixed contacts, and 10.11 is the first and second fixed contact group. 2 fixed contacts for load, 12
is a fixed contact for the cathode, 17 is a motor (load), 18 is a first holder, 19 is an operator, 22 is a first contact,
24 is a second holder, and 26 is a second contact.

Claims

[Scope of utility model registration request]

A first fixed contact group consisting of an anode fixed contact, a cathode fixed contact, and a load fixed contact connected to one terminal of the load, and an anode fixed contact and a cathode fixed contact connected to the other terminal of the load. A second fixed contact group consisting of fixed load contacts to be connected is reciprocated by an operator, and during the movement, the load fixed contacts of the first fixed contact group are connected to each of the anode and cathode fixed contacts in the moving direction. a first contact that connects in order according to the movement end position and releases the connection at the movement end position, and a second contact that is moved back and forth after a delay from the start of movement of the first contact due to the reciprocating movement of the operator and reaches the movement end position. and a second contact that connects the load fixed contact of the fixed contact group to the anode fixed contact or the cathode fixed contact depending on the movement end position of the load fixed contact, and a second contact that connects the load fixed contact of the fixed contact group to the anode fixed contact or the cathode fixed contact according to the movement end position of the load fixed contact. Due to the delay in the start of movement of the second contact, the load fixed contact of the second fixed contact group is connected to the anode or cathode fixed contact while the load fixed contact of the first fixed contact group is connected to the cathode. A polarity changeover switch device configured to display a state in which it is connected to a fixed contact for anode or anode.
