Description

A kind of mains switch

Technical field

The utility model relates to a kind of mains switch.

Background technology

Existing machinery formula mains switch generally all is to utilize to shoulder rod principle, stirs spring by button, makes to shoulder the bar contact and swing to a side joint energize under the effect of spring force, and simultaneously, indicator light is bright, the indicating circuit energized; When swinging to opposite side, deenergization, simultaneously, indicator light goes out, the indicating circuit deenergization.But, because in actual use, generally require mains switch to do for a short time as far as possible, the restriction on this size makes the distance between the binding post do very closely, causes short circuit phenomenon, and is dangerous, unreliable.

Summary of the invention

The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, proposes a kind of mains switch that can effectively prevent the indicating circuit short circuit.

Realize the technical scheme of above-mentioned purpose: a kind of mains switch, comprise pedestal 1, box body 5, instruction button 4, indicating circuit, DIP spring 8, switch spring, Roller switch 14, binding post (11,12,13) and gear projection 10, penetrate in the bottom of pedestal 1 and to fix three binding posts (11,12,13), be positioned at three binding posts (11,12,13) the rotatable box body 5 that is supported with on Shang Fang the pedestal 1, fixing instruction button 4 on the box body 5, dress indicating circuit in the box body 5, be fixed with contact 15 in power supply terminal 13 upper ends, power supply terminal 12 upper ends are provided with Roller switch 14, one end of Roller switch 14 is fixed with and contact 15 corresponding moving contacts 6, above the power supply terminal 12 over against box body 5 bottom surfaces on a fixing end of DIP spring 8, the other end compression of DIP spring 8 is supported on the Roller switch 14, an end of floatless switch spring 9 on the bottom surface of square box 5 on the power supply terminal 11, indicating circuit one termination DIP spring, another termination switch spring is in the gear projection 10 that is provided with the other end that is used to support Roller switch 14 on the bottom inside face of pedestal 1 between binding post 11 and binding post 12.

In the both sides of described pedestal 1 resilient clip 7 is set.

Described indicating circuit is in series by current-limiting resistance 2 and luminous lamp tube 3.

Adopt technique scheme, the utility model beneficial technical effects is: by between binding post 11 and binding post 12 gear projection 10 being set on the bottom inside face of pedestal 1, during energized, do not influence the connection of Switching Power Supply, and when power supply disconnects, one end of Roller switch 14 is spacing by gear projection 10, has eliminated binding post 11 and binding post 12 cause short circuit because of Roller switch 14 possibility.Action safety, reliable effectively prevents the generation of short circuit phenomenon.The utility model is simple in structure, ingenious, practical.

Description of drawings

Fig. 1 is the structural representation of a kind of mains switch in off-state.

Fig. 2 is the structural representation of Fig. 1 mains switch when closure state.

Embodiment

In conjunction with Fig. 1 and Fig. 2, a kind of mains switch, comprise pedestal 1, box body 5, indicating circuit, instruction button 4, DIP spring 8, switch spring, Roller switch 14, binding post (11,12,13) and gear projection 10, penetrate in the bottom of pedestal 1 and to fix three binding posts (11,12,13), be positioned at three binding posts (11,12,13) the rotatable box body 5 that is supported with on Shang Fang the pedestal 1, fixing instruction button 4 on the box body 5, indicating circuit is in series by current-limiting resistance 2 and luminous lamp tube 3, dress current-limiting resistance 2 and luminous lamp tube 3 in the box body 5, be fixed with contact 15 in power supply terminal 13 upper ends, power supply terminal 12 upper ends are provided with Roller switch 14, one end of Roller switch 14 is fixed with and contact 15 corresponding moving contacts 6, above the power supply terminal 12 over against box body 5 bottom surfaces on a fixing end of DIP spring 8, the other end compression of DIP spring 8 is supported on the Roller switch 14, an end of floatless switch spring 9 on the bottom surface of square box 5 on the power supply terminal 11, current-limiting resistance 2 after the series connection and luminous lamp tube 3 one termination DIP springs 8, another termination switch spring 9, between binding post 11 and binding post 12, be provided with the gear projection 10 that is used to support Roller switch 14 other ends on the bottom inside face of pedestal 1, in the both sides of pedestal 1 resilient clip 7 is set, is convenient to connect and fix mains switch.
