CN2420726Y - Safety switch - Google Patents

Abstract

The utility model discloses a safety switch which comprises a dry-reed tube, a movable positioning button, a magnet, a shell body and connecting leads, wherein, the magnet which is fixed on the movable positioning button is arranged between the movable positioning button and the dry-reed tube. A gap is arranged between the magnet and the dry-reed tube. The dry-reed tube is controlled by the magnet to be switched on or off. Both ends of the dry-reed tube are connected with the connecting leads. The utility model overcomes the defect that the general switch direct contact an electrified object. Therefore, the occurrence of a short circuit and the cause of an electric shock accident are avoided. The utility model has the advantages of simple structure and low cost, and is a product of an appliance switch of a new generation.

Description

Safety switch

The utility model relates to a kind of appliance switch, and is especially security-related with switch.

Used switch adopts direct touch controls in the existing daily productive life, and is impaired or be short-circuited easily when working under wet condition and cause electric shock accidents as switch.

It is reasonable that the purpose of this utility model provides a kind of topology layout, easy to use, can prevent the safety switch of electric shock accidents.

For achieving the above object, the utility model is intended adopting following technical solution: the utility model is by tongue tube, the running fix button, magnet, housing and connect lead and form is fixed on magnet on the running fix button between running fix button and tongue tube, leaves the space between magnet and the tongue tube, the distance that the running fix button moves is enough to make the on-off of magnet control tongue tube, and tongue tube two ends connect lead.

Described safety switch, tongue tube two ends be connected the terminal place and adopt the marine glue sealing.

The utility model has been owing to adopted above-mentioned technical solution, thereby has following beneficial effect: (one) is owing to leave the space between magnet and the tongue tube, has avoided the direct contact energising of switch, can avoid being short-circuited and causing electric shock accidents; (2) be that the marine glue sealing is adopted in the joint, even also can use under water; (3) be compactness rational in infrastructure, cost and regular tap are very nearly the same.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is the structural representation of the utility model safety switch.

Fig. 2 is the circuit diagram of the utility model safety switch.

As shown in Figure 1: safety switch is by tongue tube 1, running fix button 2. magnets 3, housing 4 and connection lead 5 are formed, be fixed on magnet 3 on the running fix button 2 between running fix button 2 and tongue tube 1, leave the space between magnet 3 and the tongue tube 1, the distance that running fix button 2 moves is enough to make the on-off of magnet 3 control tongue tubes 1, and tongue tube 1 two ends connect lead 5, tongue tube 1 two ends with is connected lead 5 joints employing marine glue 6 and seals.Described running fix button 2 adopts the structure that is similar to ball pen running fix button.

Claims (2)

1, a kind of safety switch, comprise tongue tube (1), running fix button (2), magnet (3), housing (4) and connection lead (5), it is characterized in that: the magnet (3) that is fixed on the running fix button (2) is positioned between running fix button (2) and the tongue tube (1), leaves the space between magnet (3) and the tongue tube (1), the distance that running fix button (2) moves is enough to make the on-off of magnet (3) control tongue tube (1), and tongue tube (1) two end connects lead (5).

2, safety switch according to claim 1 is characterized in that: tongue tube (1) two end be connected lead (5) joint and adopt marine glue (6) sealing.
