An adjustable mount for an electrical device (such as a limit switch) or an optical device that includes: (a) a base adapted to be mounted to a surface; and (b) a platform coupled to and elevated above the base; where the platform includes, a top surface for seating an electrical sensor device or an optical device thereon, a through-hole approximate a first end of the top surface for receiving a first screw extending from the electrical sensor device or optical device, and an arcuate through-slot approximate a second end of the top surface opposite the first end for receiving a second screw extending from the electrical sensor device or optical device, the arcuate through-slot having a radius of curvature centered near or on the through-hole.

A switch control module is provided, which includes housing, a control assembly, a linkage unit, and a number of positioning units. The housing defines an accommodating space and has an opening. The control assembly is positioned in the accommodating space and has a shaft that is rotatable about a main axis. The linkage unit passes through the opening and is connected to the shaft in a movable manner. The positioning units are positioned at the edge of the opening. Each of the positioning units extends radially and outwardly with the main axis as a center and is projected in a direction along the main axis. The linkage unit is selectively connected to one of the positioning units and is configured to drive the shaft to rotate so as to change the operation of the control module.

An electronic component comprising: a case; a switching mechanism incorporated within the case; an actuator configured to actuate the switching mechanism, the actuator being mounted in the case so as to be displaceable by sliding; and a rubber cap configured to seal a sliding part of the actuator, wherein the rubber cap is made of a hydrin-based rubber.

The present disclosure provides a drawer-type carrying device for an accelerator and an cabin structure for the accelerator, the drawer-type carrying device for the accelerator includes a frame mechanism and a drawing mechanism. The frame mechanism is used for installing the accelerator; the drawing mechanism is connected with the frame mechanism and the frame mechanism is movable relative to the drawing mechanism. The cabin structure for the accelerator includes a cabin, a shielding mechanism and a drawer-type carrying device for the accelerator. The cabin has a working area and a maintenance area. The shielding mechanism is disposed in the working area and has a side opening door facing towards the maintenance area. The frame mechanism is capable of drawn from the shielding mechanism into the maintenance area when the side opening door is opened.

Example motor assemblies for architectural coverings are described herein. An example motor assembly includes a motor, a first switch to trigger the motor to retract an architectural covering, a second switch to trigger the motor to extend the architectural covering, and an actuator positioned to activate the first switch when the actuator is rotated in a first direction and to activate the second switch when the actuator is rotated in a second direction. Also described herein are example lever actuators for motor assemblies of architectural coverings. An example lever actuator detaches from the motor assembly to prevent excess force on the motor assembly that could otherwise detrimentally affect the motor assembly.

A switchgear includes a movable part capable of reciprocating movement, a movable contact coupled to the movable part, a member that biases the movable contact, a latch capable of switching between a first state in which movement of the movable contact is restricted and a second state in which movement is permitted, a part that accommodates the movable part and the movable contact therein, a fixed contact provided outside of the accommodating part, and a moving part that moves with the movable contact. The latch is switched to the second state when the movable contact has moved against the biasing force. The accommodating part contains a first region and a second region, which is on a side of the fixed contact with respect to the first region within a range of movement of the moving part. The first region has an inner diameter smaller than that of the second region.
