Rocker switch with unique locking device

Abstract

The invention discloses a rocker switch with a unique locking device, comprising a three-gear rocker switch component and a locking device component. The inner side of a switch key cap is provided with fixing columns and screw hole columns, which are inserted into four assembly holes in a switch key. Two guide ribs are distributed on the inner side of the switch key cap. The guide ribs are clamped into guide grooves in a matching manner. A locking slider is internally provided with a D-shaped counter bore. The lower part of a locking key is provided with a D-shaped column. The D-shaped column and the D-shaped counter bore are positioned in a matching manner. When the switch key cap is pressed to OFF, the switch key cap is parallel to the end face of a base of the rocker switch, and the locking slider does not produce interference. When the switch key cap is pressed to ON2, the switch key cap tilts at an angle relative to the end face of the base of the rocker switch, the top face of a rib, outside the lateral side of the base of the rocker switch, of the locking slider is lower than the end face of the base of the rocker switch, the sliding of the locking slider is limited, and the rocker switch is locked.

Description

technical field [0001] The invention relates to the technical field of rocker switches, in particular to a rocker switch with a unique locking device. Background technique [0002] At present, three-speed rocker switches commonly have various functional forms such as single-way three-speed, double-way three-speed, single-way three-speed self-resetting, dual-way three-speed self-resetting, etc. They all have ON-OFF-ON three-speed, generally There is no locking device, and it can be quickly switched between ON-OFF-ON three gears. It only takes a short time to switch from one ON gear to OFF and then to another ON gear. When the user is in a hurry, almost It can be switched from one ON gear to another ON gear instantly by skipping the OFF gear. When these switches are installed on electric products to control their forward and reverse functions, the machine may switch from the forward rotation state to the reverse rotation state in a very short time due to the user’s quick butt...

AI Technical Summary

Problems solved by technology

When these switches are installed on electric products to control their forward and reverse functions, the machine may switch from the forward rotation state to the reverse rotation state in a very short time due to the user’s quick key operation, resulting in motor failure. Violent commutation without deceleration buffer leads to a sharp increase in current, which seriously reduces the service life of electrical products, especially motors. Especially for electrical products using series-excited motors, tongue-shaped or ring-shaped sparks will flash due to instantaneous violent commutation, and even start a fire
