LA38 - - / Button model: Issued by Shanghai Electrical Apparatus Research Institute of Mechanical Ministry and dedicated for Jiangyin Changjiang Electric Appliance Co., Ltd. Basic specification code: represents contact pair number. The first bit means dynamic closing (normally open) number and the second bit means dynamic breaking (normally close) Variety derived code: general button has no such code; “D” is with-lamp type, “S” is selflocking type, “B” is double-bit button, “X is short-handle knob, “Cx is long-handle knob, “Rx is round knob, “Y is key button, “M” is mushroom button, MS is self-locking mushroom button, “Mxs” is rotary resetting mushroom button,“Mxy” is key resetting mushroom button; J is emergency button for drawing operation. This code is a set. Product design S/n, consists of mounting neck size code ( “1” is 16mm, “2” is 22 mm , “3” is 25 mm and “4” is 30 mm), operation part shape code ( “0” is round, “2” is square and “4” is rectangle) and special structure code of enterprise. Structure code instruction:3,9B is fast moving type contact; 4, 8B is slow moving type contact. For the above structure installation part, we hold utility model patent;3,4 front panel shape are same,8B and 9B front panel shape are same; 6A, 6B and 7 is economic type, which has only two pairs of contact and among them,6A and 6B are slowmoving type contact and7is conversion type contact. Lighting part of button with lamp is applied to circuit: 2 can be used in both DC circuit and AC circuit. 4 is used in AC circuit. It can be omitted and directly expressed in words together with color and voltage, e.g. “Red AC 220V”. 1. 5. 4. 3. 2. 1. 5. 4. 3. 2.
