Slide type variable resistor with resistance adjusting member

A slide type variable resistor with a resistance adjusting member, comprising:

• a housing, having a housing position limiting hole extending along a manipulating direction, and forming an accommodation space spatially communicated to the housing position limiting hole;
• two side rails, extending along the manipulating direction and symmetrically located in the accommodation space;
• a circuit module, located in the accommodation space and having a resistor circuit;
• a manipulating device, located in the accommodation space, and comprising:
• a slidable unit, slidably located between the two side rails along the manipulating direction, and having a bump;
• at least one metal brush, fixed on the slidable unit and with elastic force to press against the resistor circuit;
• a handle, connected to the slidable unit and extending outward through the housing position limiting hole;
• and
• an elastic member, sleeved on the bump;
• and
• a base, fixed to the housing and utilized for enclosing the accommodation space to constrain the two side rails, the circuit module and the manipulating device in the accommodation space, and further having a trench for pressing against the elastic member to have the elastic member moving therein.
