The invention belongs to the field of machinery, and relates to a device capable of controlling the on-off of a micro switch through lever mechanical transmission, that is, a micro switch control device. The invention limits the maximum stroke of the piston through the bushing, avoids the contact of the switch from being pushed up, and satisfies the on-off control and reliability requirements of the precision micro switch. Provide a micro switch control device, the micro switch control device is driven by the mechanical action of the valve, including a roller, a lever, a piston, a spring, a limit bushing, a switch seat, a micro switch, a first adjustment washer , the second adjusting washer, the third adjusting washer, the support and the housing.
Description
technical field [0001] The invention belongs to the mechanical field, and is a device capable of controlling the on-off of a micro switch through a lever mechanical transmission. Background technique [0002] Existing switch control devices are usually suitable for ordinary switches with large control contact strokes and low precision requirements, but cannot effectively control and over-travel protection precision switches with compact structures and high displacement control precision, and the switch contacts may be pushed. risk of death. This will cause damage to the switch or shorten the service life, which cannot meet the use requirements of the micro switch with sensitive contacts. The control device controls the on-off of the micro switch through the mechanical transmission of the lever, and can precisely control and adjust the displacement of the lever and the initial installation position. At the same time, the maximum stroke of the piston is limited by the limit b...
