Add and used in the environment being suitble on ship, improve its service life；And protective cover is installed on housing and can be very good to protect
Shield switch, enhanced convenience when use.
Description of the drawings
It further illustrates with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the protective cover structure diagram of the present invention.
Specific embodiment
A kind of universal change-over switch as Figure 1-Figure 2, including operation handle 1 and housing 2,2 lower part of housing is provided with
Motor room 3 is provided with motor in motor room 3, and 3 lower part of motor room is provided with the circuit box 4 for the control circuit being connected with motor, behaviour
Make handle 1 and housing 2 is connected by screw 11, motor room 3 and 4 outer surface of circuit box are both provided with cylindrical shell, described
Housing 2 is cylinder, and the housing 2 is equipped with the protective cover 6 of protection operation handle 1；Protective cover 6 can protect operation handle 1,
And further protection switch capable destruction can not be put by extraneous groceries are split.
The protective cover 6 is in barreled, and including bung hole 7, ladle body 61 and bucket bottom 62, the bung hole 7 is equipped with elastic component 8, described
Elastic component 8 and 7 fixing assembling of bung hole, the bung hole 8, ladle body 61 and bucket bottom 62, which are integrally formed, to be formed.
The housing 2 is equipped with the slot 5 for accommodating elastic component 7, and the cell wall of the slot 5 is arcuate structure；Under presenting so greatly
Small structure can be very good protection operation handle 1, and use when can be with enhanced convenience.
The perimeter that the ladle body 61 connect one end with bung hole 7 is more than the perimeter 9 that ladle body 61 connect one end with bucket bottom 62.
The protective cover 6 is formed using rubber material.
