05 series: Environmental protection and non-environmental protection, with switch and without switch, real double and false double

　　1, the parts are composed of: resistance sheet, push handle, brush, shell.

　　2, the distinction between environmental protection and not environmental protection: mainly refers to whether the resistance sheet itself meets the environmental protection requirements of ROSH.

　　3, single link: that is, a common single link product, turn to the end of foot 1 or foot 3 have resistance values, there are residual resistance values at both ends (that is, 1~2 feet and 2~3 feet), for 1 foot, 2 feet, 3 feet

　　4, single-link switch, that is, one end of the resistor is printed with an insulation layer, when VR turns to the end, the brush runs to disconnect (switch) with the insulation layer

　　5, double without switch a total of 1 pin: that is, the ordinary double model, the resistor two resistor body carbon film 1 pin connected together, the existing product name is R1001G are double without switch a total of 1 pin
