Alipay deal directly; 2. Express collection of money (for customers in Guangdong province) 3. Bank transfer (for no Alipay customer) BCR50GM-12L BCR50GM supply of new RD-91 package BTA25-600B ordinary triac thyristor three electrodes can be blocked with a multimeter ohm R × 100 gear to measure. As we all know, the thyristor G, K is a PN junction between (a) the triac TG35C60, the equivalent of a diode triac bta26, G is positive, K is negative, so the test diode in accordance with a method to identify three poles of the two poles to measure its positive and negative resistance, resistance hour, multimeter black pen then the control electrode G, can teach just demonstrated with the circuit board. Turn the power switch S, click the button switch SB, light bulb is good, does not light is bad. Triac BTA40, are fertile Electronics (certified), SCR provided by the Dongguan City is Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd. (www.dgmydz.com) is Dongguan, FET leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
